Greetings from CEO

We appreciate all the customers for their deep interest in our products.

SystemBase has been engaged wholly in the field of the serial communications to produce the

various products related to the same since it was founded in 1987.

Along with the recent booming market trend by the advanced skill of high speed communication

applying LAN the applicable field of this serial communications could not draw the attention of

the public. Consequently the customers of the serial communications have faced the difficulty of

very poor technical support from the supplier in spite of its wide use before then.

But the customers of SystemBase are not needed to worry about such inconveniences since

the technical discussions with customers for the application of our products as well as the

efficient After-Service work have been kept effectively so far and will also be kept continuously

in future by the technical staffs our company who have enough experiences and skills to perfect

customers from such inconveniences.

Once again we appreciate all of our customers who have loved our products during the past

years.

About MultiPort

MultiPort is a multi serial communication device which makes PC to a multi-user or Multi device

system by applying it. Multi-user system or RAS(Remote Access System) is a system which

enables a server computer to be used together by multi users thru the terminal at distance or to

have the information used together.

All the users can access to the server thru the MultiPort equipped on the server at distance and

can use the device connected to the network as if it is his own one, or can access to the file

server as if he is on the LAN. In many cases only one computer is used simultaneously by multi

staff in the company due to the function and economic reason. What makes it possible is the

multi communication access device which connects the operating system with multi user

function and multi users. The typical ones are LAN and the asynchronous serial communication

port. Of these the device which connects the host and multi users locating at distance by using

asynchronous communication port is the MultiPort.

The multi device system is mainly used for the automation system, and it collects and distributes

the data at real time created from each device, or control various devices at distance by a

computer installed at center with several asynchronous devices connected. In other words the

user at center can work at the real time by catching the present status of all devices located at

distance, or controlling the movement of them thru the MultiPort of the computer at center.

The merit of MultiPort is easy and economic to install and maintain.

Meantime LAN has high speed to transmit data, but the more devices connected and users are

involved the more crashes among the transmitted data happens. Once such crashes happens

far more times than some level then the transmitting efficiency is declined suddenly. But it is

possible to realize Read Time without any distance limitation by applying MultiPort because it is

1:1 communication and transmitting capacity can be kept constantly even if several dozens of

port were connected.

At the same time the speed of asynchronous communication is being improved along with the

advanced technique of hardware day by day, so not necessary to worry about the

communication speed.

There are 2 types of MultiPort-Dummy and Intelligent. Dummy MultiPort is the one which has no

processor by itself. It is better in economical viewpoint than Intelligent one in case of smaller

volume in transmitting data and fewer number of port connected to system. Usually it is more

efficient to use Dummy MultiPort when the number of port is not exceeding 32. Meantime

Intelligent MultiPort is rather efficient when required to transmit large volume of data due to its

fast processing speed as it has processor by itself. Furthermore it is possible to connect several

hundreds port to a system, but costs high.

About PCI

PCI(Peripheral Component Interconnect) is a type of local bus that connects CPUs and internal

peripherals. In 1991, PCI was proposed by Intel Corporation for the first time, but now it is a

local bus standard so that PCs, and even medium and large computer systems can adopt it. A

few features of PCI bus can be summarized as follows.

The PCI is basically designed to operate at 33 MHz clock speed and 32 bit I/O. It also has an

extended 66 MHz, 64 bit I/O that accommodates Baud rates 8 times faster than the

conventional ISA bus type (8 MHz, 16 bit I/O).

Peripherals connected to the PCI bus have their own register and device information used for

setting hardware automatically. This enables users to install PCI devices with ease.

The CPU works separately from the bus master, so that the PCI bus continues to perform its

functions without waiting for the CPU even though the peripherals connected though the bus

are slow. This structure helps PCI handle much more loads at the same time.

The PCI bus has multiplexed card pins that contribute to reduce component size, making them

smaller than ISA cards and further lowering hardware costs.

PCI bus components are completely compatible with existing device drivers and applications.

That is, they only require PCI in order to control the devices and show perfect compatibility with

previously installed programs.

The PCI bus makes its surface reversely located from that of the ISA card so that it can utilize a

shared slot (using the identical guide between different bus types).

The PCI bus is the most effective supporting type for 64-bit CPU. As it has the advantage on

being compatible with the existing ISA bus, it is expected to be a standard bus type for all

computers in the future.

Isolation

What is Isolation?

ISO version boards and panels include an embedded isolator to provide isolation

feature. Isolator cuts off the electric route between the input and output by inserting an

appropriate shock absorber. This feature protects the device from the power crash.

Product Features

Securely protects the product from electric shock with opto coupler and DC-DC

converter that electrically isolate the power and signal lines.

PC internal signal and RS422, RS485 signal: 10kV Opto Isolated.

PC internal power and RS422, RS485 power: 3kV Isolated.

Synopsys

Synopsis

SystemBase MultiPort PCI boards are installed on a PCI slot of your PC, providing 1,

2,4,8,16,24 or 32 RS 232/RS422/RSs485 serial ports.

Multi-1/PCI, Multi-2/PCI, Multi-4/PCI, Multi-8/PCI MultiPort boards provide one, two,

four and eight serial ports respectively.

Multi-32/PCI MultiPort board is composed of 8, 16, 24, 32 ports with the extended

external port box, Each port complies with standard UART for both-way communication

at up to 921,600 bps.

MultiPort PCI board occupies one interrupt number (IRQ) and many I/O addresses.

MultiPort PCI board has automatic setting functions that eliminate the inconvenience of

manually setting I/O base addresses and IRQ numbers.

Each PC has up to four multiPort PCI boards and amounts to up to 128 ports.

In Multi user environments such as SCO UNIX, Linux and Windows

2000/NT/XP/2003/Vista MultiPort PCI boards operate in multi-user mode connecting

several terminals to one PC through multiplexed asynchronous serial communications.

In singular user environments such as windows 98 and MS-DOS, MultiPort PCI boards

operate in multi-device mode connecting several devices to one PC through

multiplexed asynchronous serial communications.

The MultiPort board includes

1. MultiPort controller board.

2. External port box(however, it is excluded from

3. Multi-1, 2, 4J, 8C, 16C).

4. Controller cable(however, it is excluded from Multi-1,2).

5. CD with driver manual.

Multi-1/PCI VA1

Multi-1/PCI VA1 board is a model that supports PCI Local Bus Spec 2.3. It is an asynchronous

single port product designed to automatically set I/O address and IRQ number when ROM bios

or the operating system starts. Unlike former products, Multi-1/PCI uses core for PCI Local Bus

Spec 2.3 designed by SystemBase. Multi-1/PCI VA1 not only supports maximum

communication speed of 921.6Kbps but also provides advanced ability to automatically control

IO signals when it is used with driver provided by SystemBase. Furthermore, it is equipped with

surge protector to protect internal systems from outer shock. Unlike former products, all

information about the board is contained within the board itself so the users can easily know

information such as number of ports currently installed, maximum communication speed, kind of

communcation controller and etc. Also, LED is attached outside to show the current status of

signal lines.
